CLOSED-EN'D-BOILER STAND.

Application filed. March 6, 1924.

This invention relates -to range boiler stands of that type comprising a base and a hollow pedestal open at its upper end and threaded at said end into the bottom wall of the boiler. Stands of this type are generally objectionable for the reason that lime and other sedimentary matter accumulate in the hollow pedestal thereof, and the object of my invention is the provision of a stand of this type which shall be free from this objection, and to attain this end I close the upper end of the pedestal by a wall forming an integral part of the pedestal and having a convex outer surface so as not to interfere with the threading of the pedestal into the bottom wall of boiler.

. The invention is hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in side elevation of a standard boiler supported by'a pedestal constructed in accordance with my invention, and

Figure 2 is a sectional view taken on the vertical plane indicated by the line 2-2 of Figure 1.

Referring to the drawing by reference numerals, 1 designates a boiler of standard construction having in the top wall thereof the usual hot and cold water connections 2 and 3, respectively, and having in the side wall thereof the usual connections 4 and 5 for the heater.

The stand upon which the boiler rests comprises a hollow base 6 and a hollow pedestal 7. The base and pedestal are preferably formed integrally, and the latter is provided at its upper end with a screw thread 8 to permit it to be threaded into an opening 9 in the bottom wall of the boiler. The central part of the bottom wall of the boiler, in which part the opening 9 is formed, is of increased thickness'to permit of a substantial connection being established Serial No. 697,348.

the upper end of the pedestal into the bottom wall of the boiler.

As the stand is of hollow formation it may be cheaply manufactured. As the pedestal has its upper end closed there is no possibility of lime and other sedimentary material accumulating therein, and as the upper end wall of'the pedestal is convex the pedestal may be readily and quicklythreaded into the opening in the bottom wall of the boiler.

It is to be understood that the drawing is merely illustrative and does not pretend to give the exact proportions.

VVhatis claimed is In combination with a range boiler having the bottom wall thereof provided with an integral central part of increased thickness, said part extending inwardly and outwardly beyond said wall and provided with a threaded opening, an integrally formed hollow base and pedestal, said pedestal tapering from its lower to its upper end and having its upper end screw threaded and positioned in the opening in the bottom wall of the boiler, and said pedestal having its upper end closed by a wall formed integrally therewith and provided with an outer convex surface to facilitate threading of the pedestal into said opening.

In testimony whereof I aflix my signature.

JOHN J. DIVEKEY.
